2.
Make the connections.
a.
Connect the four pin female header of the Communication/Power Cable to the
Communication/Power Header of your LK204-7T-1U.
b.
Insert the male end of your serial cable to the corresponding DB9 header of the
Communication/Power Cable and the mate the female connector with the desired
communication port of your
computer.
c.
Select an unmodified floppy cable from a PC power supply and connect it to the power header
of the Communication/Power Cable.

uProject or a terminal program will serve to get you started, and then move on with your own
development. Instructions for the former can be found below and a variety of application
notes are available for the latter at www.matrixorbital.ca/appnotes.
I2C
Connections
A more advanced connection to the LK204-7T-1U
is provided by the I2C protocol setting. This is best
accomplished using a breadboard and the Breadboard Cable. Power must be supplied from your
breadboard or another external source. To dive right into your application and use the LK204-7T-1U
in
I2C mode, get started with the guidelines below.
1.
Set the Protocol Select switches.
?
I2C: Ensure that the two I2C jumpers in the corresponding protocol box are connected while all
others are open.
2.
Make the connections.
a.
Connect the Breadboard Cable to the Communication/Power Header on your LK204-7T-1U
and
plug the four leads into your breadboard. The red lead will require power, while the black
should be connected to ground, and the green and yellow should be connected to your
controller clock and data lines respectively.
b.
Pull up the clock and data lines to five volts using a resistance between one and ten kilohms on
your breadboard.
3.

This time you're on your own. While there are many examples within the Matrix Orbital
AppNote section, www.matrixorbital.ca/appnotes, too many controllers and languages exist to
cover them all. If you get stuck in development, it is possible to switch over to another protocol
on the standard board, and fellow developers are always on our forums for additional support.
